Differential Toxicity and Uptake of Two Fenvalerate Formulations in Fathead Minnows (Pimephales Promelas)
The influence of the commercial emulsifier on the acute toxicity and uptake of fenvalerate [(R,S)-αcyano-3-phenoxybenzyl(R,S)-2-(4-chlorophenyl)-3-methylbutyrate], a synthetic pyre-throid insecticide, by fathead minnows (Pimephales promelas) was examined. Flow-through acute toxicity testing with measured concentrations of technical-grade fenvalerate and a 30% active ingredient emulsifiable conc...
متن کاملBehavioral avoidance of fluoranthene by fathead minnows (Pimephales promelas).
A monitoring system was used to examine the behavioral response of fathead minnows (Pimephales promelas) to plumes of the polycyclic aromatic hydrocarbon fluoranthene. Previously unexposed fish and fish surviving acute exposure to fluoranthene were presented with three different concentrations of fluoranthene. Both groups of fish avoided fluoranthene. Pre-exposure did not enhance or diminish av...
متن کاملDetermination of vitellogenin kinetics in male fathead minnows (Pimephales promelas).
A lack of knowledge persists concerning the combination of kinetics on protein and mRNA levels of the most commonly used biomarker for estrogenic influences-vitellogenin (VTG). Consequently, male fathead minnows were exposed to 17alpha-ethinylestradiol (EE(2)) for 35 days, followed by an equally long depuration period in a flow-through system. VTG mRNA levels reached a plateau after 3 days of e...
متن کاملEvaluation of acute copper toxicity to larval fathead minnows (Pimephales promelas) in soft surface waters.
The hardness-based regulatory approach for Cu prescribes an extrapolation of the toxicity-versus-hardness relationship to low hardness (< or =50 mg/L as CaCO3). Hence, the objective of the present research was to evaluate the influences of water quality on acute Cu toxicity to larval fathead minnow (Pimephales promelas) in low-hardness surface waters. Seasonal water sampling was conducted at 24...
متن کاملToxicity of oil sands to early life stages of fathead minnows (Pimephales promelas).
The present study examines the effects of exposure to oil sands on the early life stages (ELS) of fathead minnows (Pimephales promelas). Sediments within and outside natural oil sand deposits were collected from sites along the Athabasca River (AB, Canada). The ELS toxicity tests were conducted with control water, natural oil sands, reference sediments, and oil-refining wastewater pond sediment...
